The Simpsons had another split-second tribute to the late Marcia Wallace on Sunday

While a genuine sendoff to the late Marcia Wallace has yet to be integrated live into The Simpsons’ broadcasts, owing to the terrible strain it would put on the animators’ wrists, the show has been making do with shorter tributes in the meantime. First there was the saddest chalkboard gag you’ve ever seen. Then, during Sunday’s Christmas episode, came another split-second acknowledgement during the overstuffed credits—an acknowledgement you might have missed unless you were looking very, very closely.
